1.	The Dean campaign made a big mistake, imho, by getting into the software business. Now it looks like the Edwards campaign is following them. Software and the candidates should be separate. A blogging tool can just as easily be used to advocate for a Republican or a Democrat.
2.	Build on what the weblog development community has accomplished, and will continue to accomplish through November next year. Be open to users of all platforms. You can get the leading weblog tools vendors to help your candidacy and to help the election, but not if you exclude them from participating in your campaign!
3.	Users of software tools don't generally want to switch, so don't try to make them do it just to support your campaign. Again, think about bringing more bloggers into your tent, not creating a tent that excludes existing bloggers. Let weblogs grow independently of your campaign, no matter how big you are, they will anyway.
